Configuring DHCP on a Palo Alto firewall looks like a two-minute job until the clients do not get an address. In this video I build a working DHCP server, then a working DHCP relay, and I show the typical configuration mistakes. Covered: what auto mode actually does, ping before allocation, lease types, IP pools and MAC reservations, the DHCP options tab including inheritance from your WAN interface and custom options like 150 for IP phones, then relay configuration and the reason it must sit on the client-facing interface. 🌐 USEFUL LINKS NETSums Resources: https://netsums.com/resources Join the community for FREE: https://netsums.com/join 👍 LIKE, SHARE AND SUBSCRIBE FOR MORE If you enjoyed getting to know me, give this video a thumbs up, share it with your colleagues, and subscribe for more in-depth tutorials on network security and Palo Alto Networks. 🔗 CONNECT WITH US Questions, suggestions, or feedback?

Palo Alto Firewall DHCP Explained (Server, Relay, Options and Reservations)
An authentication sequence lets a Palo Alto firewall try several authentication profiles in order until one of them authenticates the user. In this video I build a sequence from LDAP, RADIUS and local, then test users from each. I cover the "use domain to determine authentication profile" option and why it makes logins noticeably faster, how per-profile allow lists cause failures that look exactly like a wrong password in the logs, and the timeout trap that makes GlobalProtect logins fail intermittently. Finishes with the test authentication CLI command, which show you which profile matches the authentication. 🌐 USEFUL LINKS NETSums Resources: https://netsums.com/resources Join the community for FREE: https://netsums.com/join 👍 LIKE, SHARE AND SUBSCRIBE FOR MORE If you enjoyed getting to know me, give this video a thumbs up, share it with your colleagues, and subscribe for more in-depth tutorials on network security and Palo Alto Networks. 🔗 CONNECT WITH US Questions, suggestions, or feedback?

DNS Proxy turns your Palo Alto firewall into a DNS resolver, and it a secure way to do split DNS at a branch without deploying another server.
